Yes, that was likely contributing. The Node#addNode call without
specifying a node type argument will choose the child node type by
inspecting the child node definitions for the parent node type (nt:folder
in this case). A quick look at the nt:folder node type definition shows
that it allows children with any name whose node type is "nt:heirarchyNode"
(or derived from that type).
I haven't tried this, but I believe in your example it may have
chosen "nt:heirarchyNode" as the node type for the new child which wouldn't
be valid since that is an abstract node type.
Adding the JcrConstants.NT_FILE argument to the addNode call makes the
configuration valid for a child of an nt:folder node.
